Description

Technical Field

[0001] This invention relates to the field of bridge engineering construction technology, and in particular to a non-interrupted transverse jacking construction system and method for skew-crossing bridges. Background Technology

[0002] In existing technologies, the construction of overpass bridges that cross existing railway, highway, and other operational lines generally faces the challenge of traffic disruption or severe restrictions. To avoid interference with the existing lines below, traditional construction methods often employ full-span scaffolding for cast-in-place or segmented prefabrication and erection of the superstructure. However, these methods require the construction of a large number of temporary support systems directly above the existing lines, which not only results in long construction periods and large land occupation, but also, in the case of skew bridges, because the bridge axis is not orthogonal to the existing lines, the support system is prone to misalignment, torque, and uneven settlement, significantly increasing safety risks.

[0003] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0016] A method for uninterrupted transverse jacking construction of an skew-crossing bridge includes the following steps: S1: Site preparation and platform setup: On the side of the existing line, multiple independent assembly supports are constructed along the design direction of the bridge to form a side assembly platform. A lateral sliding mechanism consisting of basic slide rails is installed on top of the assembly bracket; S2. Side assembly of the superstructure and installation of the jacking system: On the side assembly platform, the bridge superstructure is assembled into a complete structure. A translational base frame assembly is installed on the basic slide rail, and the translational base frame assembly is securely connected to the starting end of the bridge superstructure through a stabilizing unit. A guide beam assembly is installed on the translational base frame assembly, and an extended guide beam extends from the front end of the guide beam assembly; S3. Quick-connect bridge frame erection and track connection: A quick-erecting bridge frame mechanism is erected between the adjacent assembly platform and the first overpass pier; One end of the quick-set bridge frame mechanism is connected to the assembly bracket via a locking frame assembly, and the other end is connected to the column of the cross-road bridge pier via a fastening slide. Adjust the auxiliary sliding mechanism on the quick-connect bridge mechanism so that its auxiliary track smoothly connects with the base slide rail of the transverse sliding mechanism; S4. Lateral jacking construction: The lateral moving component set on the basic slide rail is activated, driving the translation base frame component to carry the entire bridge superstructure and push it laterally. During the jacking process, when the front end of the guide beam assembly reaches the quick-connect bridge mechanism, its posture is adjusted by the auxiliary elevation unit to smoothly transition it onto the auxiliary sliding mechanism. The extension length of the guide beam assembly is adjusted using the lateral extension and retraction components, and the bridge attitude is adjusted in real time using the first and second control components. When the front end of the bridge superstructure approaches the pier in front of the road, guide it into place; S5. Structural fine-tuning and system conversion: After the jacking is completed, the first and second control components are used to perform three-dimensional fine-tuning of the bridge superstructure. Transfer the bridge superstructure from the translational support frame assembly to the permanent bearing; S6. Temporary structure removal: The lateral sliding mechanism, the quick-connect bridge mechanism, and the side assembly platform were dismantled in sequence.

[0017] In step S4, the lateral movement component employs a step-by-step pushing cycle, specifically including: Pushing steps: Lock the transverse base, retract the transverse base rod, and drive the translation base frame assembly forward one stroke; Locking procedure: Lock the translation base frame assembly to the base slide rail; Return procedure: Unlock the transverse base, extend the transverse base rod, and push the transverse base forward along the foundation slide rail to reset; Preparation steps: Unlock the translation base frame assembly to prepare for the next cycle.

[0018] This invention transfers all high-altitude assembly operations to an area with "zero impact" on traffic under the bridge by setting up an independent side-mounted assembly platform on the side of the existing line. This fundamentally eliminates the interference and safety risks of construction on line operation, and is particularly suitable for busy trunk lines where traffic interruption is not allowed.

[0019] The quick-erecting bridge structure in this invention serves as a rapidly installable and disassembled transition bridge, enabling rapid erection between the adjacent platform and the permanent pier. Its auxiliary sliding mechanism seamlessly connects with the base rail of the lateral sliding mechanism. This provides the jacking equipment with a continuous track and intermediate support across the piers, a key technology for achieving long-distance, uninterrupted lateral jacking of the entire bridge.

[0020] This invention integrates a step-driven lateral movement component, an actively adjustable correction guide wheel unit, and multiple first and second control components distributed on the translation base frame and guide beam. These components work collaboratively under the real-time monitoring of displacement sensors and positioners, enabling dynamic and precise control of the jacking trajectory of a bridge structure weighing thousands of tons. Furthermore, their attitude can be finely adjusted in three dimensions throughout the jacking process, effectively overcoming the complex deflection torque generated by skewed jacking and ensuring that construction accuracy and structural stress remain within a safe and controllable range.

[0021] The basic slide rail of the lateral sliding mechanism adopts a modular splicing design to adapt to different spans. The stabilizing unit uses a combination of rigid clamping and flexible covering to ensure reliable transmission of the jacking force. Multiple mechanical locking mechanisms, such as the positioning and locking unit and the bidirectional compression assembly, ensure the absolute stability of each component connection under dynamic loads.

[0030] See Figures 1 to 7 As shown, a non-interrupted skew-crossing bridge displaced and integrated transverse jacking construction system includes at least two cross-road piers 110 arranged at intervals along the bridge's design route. The side-mounted assembly platform 120 is located to the side of the existing line, that is, to the side of the final placement line of the bridge, rather than directly below it, thereby avoiding high-risk high-altitude assembly operations directly above the existing line. It includes several assembly supports 121, and the ground projection of each assembly support 121 is collinear with the ground projection of the corresponding cross-road pier 110, ensuring that the subsequent lateral jacking path is accurate and straight. The lateral sliding mechanism 200 is set on the side assembly platform 120. As the core drive and load-bearing structure, it is responsible for smoothly and accurately pushing the assembled bridge superstructure 130 from the side across the existing line to the designed bridge site. The quick-assembly bridge frame mechanism 300 has its two ends detachably connected to the assembly bracket 121 and the adjacent cross-road pier 110, respectively. Its core function is to quickly and stably erect a temporary, detachable aerial track support platform between the side assembly platform 120 and the cross-road pier 110 during the jacking process. This platform is used to support and guide the lateral sliding mechanism 200 across the unsupported section between the piers, thereby achieving continuous transmission of jacking force and stable transition of the jacking structure. An auxiliary sliding mechanism 400 is provided on the quick-connect bridge mechanism 300 and cooperates with the transverse sliding mechanism 200. Its main function is to connect with the transverse sliding mechanism 200 to form a continuous jacking track or support surface, and to provide auxiliary support and guidance for the bridge superstructure 130 during jacking when it crosses the quick-connect bridge mechanism 300, so as to ensure seamless connection and structural safety during the jacking process.

[0031] Furthermore, the assembly bracket 121 is configured as a temporary support structure independent of the overpass pier 110, including at least two columns 111 and a load-bearing crossbeam 112 connected to the top of the columns 111.

[0032] The foundation of the assembly bracket 121 is an independently cast concrete foundation or an enlarged steel base laid on a hardened foundation.

[0033] Preferably, the assembly bracket 121 further includes multiple stabilizing connecting rods disposed between adjacent columns 111 to form a spatially stable frame.

[0034] Furthermore, the side-mounted assembly platform 120 also includes a transverse connecting beam connected to the top of the adjacent assembly brackets 121, and a platform panel 122 laid on the supporting plane formed by the assembly brackets 121 and the transverse connecting beam. The platform panel 122 forms a construction plane for assembling the bridge superstructure 130. The transverse connecting beam connects the individual assembly brackets 121 into a whole, forming a continuous platform with high rigidity and load-bearing capacity, providing a safe and spacious working surface for the overall or segmental assembly of the bridge superstructure 130.

[0035] Furthermore, the lateral sliding mechanism 200 includes a slide rail platform 210 mounted on the assembly bracket 121. The slide rail platform 210 is provided with at least two basic slide rails 220 that cooperate with the auxiliary sliding mechanism 400. The basic slide rails 220 form the reference track for the jacking operation. A translation base frame assembly 230 is mounted on the basic slide rails 220, and a guide beam assembly 237 is mounted on the translation base frame assembly 230. The translation base frame assembly 230 serves as the main body that directly supports and drives the bridge superstructure 130, while the guide beam assembly 237 serves as its forward-extending guide and support arm. A lateral movement assembly 240 is provided on the basic slide rails 220 for driving the translation base frame assembly 230 to move laterally. The translation base frame assembly 230 is equipped with several first adjustment components 260, which are used to make local fine adjustments to the bridge superstructure 130 during the jacking process to correct any possible deviations or deformations. The guide assembly is equipped with several second adjustment components 270, which are mainly used to adjust the posture and elevation of the front end of the guide beam assembly 237 on the quick-lay bridge frame mechanism 300 or the pier to ensure a smooth transition. The translation base frame assembly 230 is also equipped with a lateral extension and retraction component 280 that cooperates with the guide beam assembly 237. The lateral extension and retraction component 280 is used to control the extension and retraction of the guide beam assembly 237 relative to the translation base frame assembly 230 to adapt to different span requirements and to achieve power transmission relay or docking with the auxiliary sliding mechanism 400 during the jacking process.

[0036] Furthermore, the base slide rail 220 includes several parallel slide rails 221 with rectangular cross-sections. Supporting ribs 222 are provided in each parallel slide rail 221, and docking base rods 223 are provided in each parallel slide rail 221. A docking insertion rod 224 is provided at one end of each docking base rod 223, and a docking insertion cylinder 225 is provided at the other end of each docking base rod 223. The docking insertion cylinder 225 cooperates with the docking insertion rod 224 or the quick-connect bridging mechanism 300. This design enables modular segmented splicing of the base slide rail 220 itself, and also provides an interface for quick and precise connection with the auxiliary rail 410 on the quick-connect bridging mechanism 300, which is crucial for achieving continuous extension of the jacking rail.

[0037] Preferably, the bottom of the parallel slide rail 221 is provided with a slide rail base 226 connected to the slide rail frame 210, or the parallel slide rail 221 and the slide rail frame 210 are integrally formed.

[0038] Furthermore, the translational base frame assembly 230 includes a translational slide 231 that cooperates with the base slide rail 220. A stabilizing base 232 is provided on the translational slide 231. A stabilizing unit 233 is provided on the stabilizing base 232 to fix the translational base frame to a section of the bridge superstructure 130, ensuring a reliable force transmission connection between the jacking drive device and the bridge superstructure 130, and preventing relative sliding or separation. Two sets of correction guide wheel frames 234 are symmetrically arranged on both sides of the translation slide 231. Each set of correction guide wheel frames 234 includes several correction guide wheel frames 234 arranged along the moving direction of the translation slide 231. The correction guide wheel frame 234 is provided with a correction guide wheel unit 235 that cooperates with the side assembly platform 120 and / or the slide rail platform 210. Its function is to constrain and guide the lateral direction of the translation slide 231 through the correction guide wheel unit 235 during the jacking process, correct the lateral deviation caused by uneven load, uneven track or manufacturing error in real time, and ensure the straightness of the jacking trajectory. The translation slide 231 has a symmetrically arranged slide rail base 236 that cooperates with the first adjustment component 260 on one side. The translation slide 231 has a guide beam groove that cooperates with the guide beam component 237 at the center. The guide component is located between the two slide rail bases 236. The guide beam assembly 237 includes a base guide beam disposed in the guide beam groove, and an extension guide beam is provided at one end of the base guide beam near the cross-bridge pier 110. The extension guide beam can extend further forward to reach the quick-erecting bridge frame mechanism 300 or the pier in front in advance to achieve a smooth transition. The translation slide 231 is provided with a positioning and locking unit that cooperates with the lateral extension and retraction assembly 280 to lock the guide beam assembly 237 after it has been extended and retracted into place, forming a rigid force transmission structure. The extension guide beam is provided with an auxiliary elevation unit, which is used to finely adjust the elevation of the end of the guide beam assembly 237 in the cantilever state of the front end, so that it is precisely matched with the front support point.

[0039] Furthermore, the stabilizing unit 233 can adopt the following structural design: Firstly, the stabilizing unit 233 includes a stabilizing carriage that slides with the stabilizing base 232, and a stabilizing control component for controlling the sliding movement of the stabilizing carriage. The stabilizing carriage is driven by the stabilizing control component to press tightly against a predetermined part of the bridge superstructure 130, forming a frictional or mechanical self-locking stable connection.

[0040] Preferably, the stabilizing unit 233 further includes a shock-absorbing base plate, and a plurality of shock-absorbing springs are disposed between the shock-absorbing base plate and the stabilizing slide. When the jacking starts, stops, or encounters minor obstacles, the shock-absorbing springs can absorb impacts and vibrations, protecting the bridge structure and the translational base frame assembly 230.

[0041] Furthermore, the damping substrate is provided with a wear-resistant coating, which improves the wear resistance and coefficient of friction of the contact surface with the bridge structure.

[0042] Secondly, the stabilizing unit 233 includes several stabilizing winches mounted on the stabilizing base frame. Each winch is equipped with a stabilizing flexible fabric that cooperates with the bridge superstructure 130. One end of the stabilizing flexible fabric is wound around the winch, and the other end is detachably connected to the stabilizing base frame 232. By tensioning the flexible fabric with the winches, it is wrapped around and tightened onto the bridge superstructure 130, achieving a flexible connection. This is suitable for situations with complex structural shapes or where the concrete surface needs protection.

[0043] Thirdly, a combination of the two structures mentioned above can be used.

[0044] Furthermore, the positioning and locking unit includes two sets of positioning and locking modules symmetrically arranged on both sides of the foundation guide beam. Each set of positioning and locking modules includes several positioning and locking modules arranged along the direction of the foundation guide beam. Multi-point locking ensures the connection strength and stability of the guide beam assembly 237 when subjected to complex loads such as jacking and turning.

[0045] The positioning and locking module includes a locking base rod disposed on the stabilizing base frame 232, and a locking insert rod disposed on the locking base rod. Correspondingly, a locking slot is provided on one side of the foundation guide beam.

[0046] Preferably, the base guide beam is provided with a locking groove that mates with the locking slot, and the locking rod is provided with a locking block that mates with the locking groove.

[0047] Furthermore, the auxiliary elevation unit includes several telescopic guide wheel modules disposed on the extended guide beam, which are used to provide temporary rolling support when the extended guide beam is suspended, reducing friction and deflection. Several telescopic threaded seat modules are disposed on the extended guide beam, which are used to extend the threaded base and make close contact with the lower support surface platform through a washer or adjusting nut when the front end of the extended guide beam needs to be precisely leveled or a rigid support point is provided, forming a stable support point.

The top surface of the transverse base 241 has several locking slots 249 along its direction. A transverse base rod 245, which cooperates with the top support base 243, is provided on the transverse base 241. Both ends of the transverse base rod 245 are rotatably connected to the transverse base 241 and the top support base 243, respectively. A first locking rod unit 246 is provided on the transverse base 241, and a second locking rod unit 247 is provided on the top support base 243. The structure of the first locking rod unit 246 is identical to that of the second locking rod unit 247. Correspondingly, a positioning slot 250 is provided on the basic slide rail 220. The transverse base 241 has a locking area for the operation of the second locking rod unit 247. Displacement sensors and positioners are provided on both the transverse base 241 and the top support base 243. Furthermore, the structure of the first control component 260 is the same as that of the lateral movement component 240, and the structure of the second control component 270 is the same as that of the lateral movement component 240.
